Chariot ready to go in deep in two offshore blocks
Oil and gas exploration firm, Netherland Sewell and Associates, has identified five potential drill sites in two offshore blocks off the coast of Namibia saying Block 2312 and 2412A, respectively show potential geological success of up to 29%.
The exploration work done on behalf of the UK explorer, Chariot Oil & Gas, is dependent on Netherland Sewell and Associates’ independent audit of 6,100 km2 of 3D seismic data. In each of these prospects, two or more drilling targets have been identified.
Netherland Sewell and Associates estimate gross mean prospective resources for each prospect ranging 283 to 459 mmbbls (million barrels). The company said that it is undertaking a contract strategy to identify an appropriate drilling unit, secure long-lead items such as wellheads and tubulars, arrange for all auxiliary services and establish a logistic base for well services, supplies, helicopters and medivac.
Chariot Oil & Gas said that the current drilling focus area was identified in the north-western area of the Central Blocks from approximately 1,700 km of proprietory 2D seismic data acquired in 2015 via a partnership.
In the drilling consortium, Chariot hold a 65% interest with the rest in the hand of partners, AziNam with 20%, Namcor with 10% and Ignitus Oil & Gas, the local partner, with 5%.
The initial scope of work will be managed through Chariot’s in-house team supported by the Country Manager and Senior Staff Drilling Engineer, Robert Mwanachilenga, who was responsible for in-country support for the Tapir South-1 deep water well operated by Chariot in 2012.
The target, Mwanachilenga said, is to undertake this drilling in the second semester of 2018 as the process continues to put together an in-house team between the partners. Chariot CEO, Larry Bottomley commented that the focus for Chariot is the delivery of transformational value through the discovery of material hydrocarbon accumulations.
“These new findings based on prior geological data of dip-closed prospects target the same good quality Upper Cretaceous deepwater turbidite reservoirs as penetrated in the Murombe-1 well and are modelled to have received hydrocarbon charge from the proven, excellent quality Aptian marine source rocks identified in both the Wingat-1 and Murombe-1 wells” stated Chariot.
“The maturation of the portfolio in the Central Blocks in Namibia has uncovered a series of robust, low-risk structural traps that are targeting the proven play elements demonstrated in nearby wells” Bottomley said.
Together with its partners, Chariot completed the acquisition of a 3D seismic survey of approximately 2,600 km2 in February 2016. “The 2016 3D survey has been processed in conjunction with 3,500 km2 of legacy 3D seismic data with both depth migration and inversion products calibrated using the nearby Wingat-1 and Murombe-1 wells,” Bottomley said.
